The rods 20 and 2l have thereon .near their forward ends the adjpstable collars 22 and 23, the springs 24 and 25 being tensioned around the rods'between the heads -16 and 17 and the collars 22 Iand with tendency to push the rods forwardly, the

' having rearwardly turned ends. The fender 30 is provided on its rear near its ends with. the yokes 31 vand 32 to which the heads 28. and 29 are pivotally connected whereby pivotal movement of lthe fender is permisled.

Thus it will be vseen thatl a fender is pro-r vided which,` in outlying or districts lwhere the traffic is not crowded may be spaced laway a decided distance lfrom the front of thevehicle andwhichwhen brought into contact with an obstacle travels inwardl towards the front of the, vehicle througil 'relatively long space, during `'which travel the shock is received by the springs 24 and v2 5 and 18 and 19, and all conducing to the protection 0f the front of the vehicle from injury.

Referring to Figs. l. 2, 4 and 8, the sector bracket 33 is secured at its lower end to the 4'cross-sill 13 inA positionadjacent to the sill 13.

' keyed atl its head portion to the shaft 35 for The -lever 33 having a segmental head portion 39 with a recess 40 therein, is

rotating the shaft, the lower end of the' 4lever' 38 being pivot'ally connected-to the head of the plunger 41, the purpose of the recess 40 being later stated.

The casing 42 issecured at its -rcar end to the cross-sill 43, this casing having the slot 44 in the upper side of its forward end, and

having througlrits rear wall the aperture 45, thev cross-Sill 43 having therethrough The rods 20 and 2t have on their for` amarre apertures registering with the aperture 45.

The stemv46 of the piston head and ratch 47 passes through the Yapertures of the cross sill 43 and through the aperture 45l and has on its, forward end the combinedA piston head and ratcht the engaging 'face 48 of the ratch extending upwardly through the slot 44. The combined piston Y head and ratch is pivotally connected to the hollow/cylindrical member 47" having the vair vent 49.-l the plunger 41 being movable in the cylindrical member 47.l The-actuating spring 50 is ar ranged inthe interior of the casing 42 between` the rear wall of the leasing and the combined piston head and ratch 47, the tendenc ofi this spring being to move' the piston lead andfratch forwardly. vThe stem 46 of the piston'head and ratch'ispivotally connected at its rear end to the link v51 havingV the elongated slotted end 52', to which the link 53 is connected for swinging movement of the link, this link being secured at its lower end to the compensating axlev 54 of the emergencyy brake ofthe vehicle for operating the brake.

y The pawl 55 is xedly secured tothe shaft 56 for movement with the shaft, the' shaft being j ouinalled at its ends on the side sills. The pawl 55 has as part thereofv and mov'- able therewith the forked member 56. which straddles the pin 57 (Fig. 3) fixed on the exterior of the tubular member 10.`- l

lt will be noted that if the' tubular members 10 and 11 are moved rearwardly through contact with an'obstacle, due to thev .movement of the pin 57 with the tubular member 10 and the engagement of said pin with the forked member 56', the pawl v55 will be moved upwardly and out of engagement with the face 48 of the ratch. whereupon the actuating spring 50 then being in compressed position it willbe released, and acting on the combined piston head vand ratch 47 will move the plunger 47 forwardly and also will thereby exert forward pulling force upon the link 51A and in turn upon the link 53 for thereby applying the emergency brakes.

For setting pr compressing the spring 5() after application of the emergency `brakes, without necessity for the driver to leave his seat, the emergency brake hand ilever 37 on the handle thereof is providedA pressed by the spring 62, the lowerendxof the rod being engageable in therecees40 in the head of the lever 38, whereby the handlever 37 and the lever 38 are by`opera` tion of the-grip lever 58 held in rigid relation for compressing the spring 50 when' i the lower end ofsaid rod is engaged in said recess, theirod 59 when the spring 50 is lompressed 'and held by pawl 55 being l i ing lever will be 4ing the emergency brakes ofthe vehicle I disengageable lease of the griplever 58. vThe brake lever from the '-recess 40 by re- .,137 has on its side opposite to the rod 59 the swinging lever 62 pivoted on the lug 63 on the brake4 lever 37. The lever 62 is normally outwardly pressed at its lower end by the spring 64 secured to the side of :the

- jhand lever 37, -and is outwardly pressed reduces, zio.

at its upper end by the'lower endA of the grip lever 65 pivoted on the lug 66 on the side of the hand lever 37, this outer pressure tending to press the lower end of the swinging lever inwardly against the spring 64. Thus when the grip lever 65 is in the posit-ion 65 shown in Fig.' 5, the swing- |engaged in one of the recesses 66 of the sector bracket 33 Awhereby the hand lever 37 is maintained in either. forward, vertical or rearward position, the

swinginglever4 62 being. disengageable from any lrecess 66 byoperation of the grip lever 65, whereby 'the brake hand lever 37 may also tion of compressing the spring 50.

Referring-to Figs. 2, 7'and 8, for applywith rapidity which is substantially instantaneous but in a'manner which greatly if not entirely obviates, the shock 'of the application, the tubular member 67 is pivotally connected at its forward end as iat 68. to the lower end ofthe brake levei 37. The tubular member 67 comprises `tlie forward extension 69 and the enlargement 70. The interior of the enlargement 70 has at its rear end the apertured head 71.

and communicates at its forward end with theinterior of the extension 69.- 'lhe enlargement 70'has therein tliepiston plunger 72, the. piston head 73 of which engages the interior of'tlie enlargement 70 in air tight manner and the plunger portion of which engages in air tight manner' the interior of the extension 69.which is closed at its forward Aend except for the air vent 74. The stem 75 of t-he plungerextends rearwardly through the head 71 and is piv otally connected to the upper end of the link 76 which is pivotally connected at its lower end to the compensating'rod 77 of the emergency brake of the vehicle, the link 76 being arranged in parallelism to the link 53 and pivotallv connected thereto by the cross link 78. The spring 79 is arranged in the. interior of the enlargement 7 0 around the stem 75 between the head 71 and the piston head 73, and the' spring 8O of greater strength than the spring 79 is arranged in the interior of the extension 69 between tlie end cf the pliingei' and the front end wall of. said interior, the tension o* the spring 79 being sulcient vto retain tlie end of the plunger in engagement with 'the end of the spring 80. ie lunger portion of the piston plunger-72 as longitudinally piston plunger be moved freely after the operaf.

will be noted upon contact -of the fender 39 with an obstacle and expansion of the spring 50, the link 53 will be pulled frwardly, and through cooperation of the cross llink 7S the link 76 will be pushed forwardly hereby forcing forwardly the 7 2 vvwhich compresses. the

spring 80 andcompressesthe air in the interior of the extension 69 and enlargement 70, the compression -of the spring 80 and said air counteracting the expansion of the spring 50, and-while permitting rapid and substantially instantaneous expansion of thespring 50 when an obstacle is struck by the fender30, the emergency brakes are applied in such manner that the shock or jar upon the vehicle is very greatly. mitigated. Referring to Figs. 1, 4, 5 and 6, for making andbreaking the ignition circuit, the bracket 36 secured totlie cross-sill 13 supports the dielectric disk 83 having thereon raised segmental portions 84 and 85 between which are secured thev segmental portions 86 and 87 of conductive material, the portions 86 and 87 being provided with the 'binder posts 88 and 89 connected by the wires 90 and 911to the'ignition circuit of the vehicle.

'The hub 92 of dielectric materialis movable 94 in contact withthe` -isk- 83." Thus it will be noted that, if .tlie shaft 35 be partially rotated by' the lever `38,.Fig. 4, upon contact of thefender 30 with an obstacle while the ends a 1 1 96,0f the plate 94 are 'in con.- tact with'th'e 'portions'.'86 and 87 of the diedi 83, these ends wllbe moved into Contact :with the portions 84 and 85 of the disk 83,

whereby the ignition circuit will be broken 0r cutaiid firing ofthe gases in the engine cylinders will be prevented. Due to momentuin of the engine pistons the unfired gases will 'be compressed in the cylindersv thereby, if the clutch of the engine has not been released, applying additional brake effect upon the rear wheels of the vehicle.

lVhen the device is again set by the driver for application of tlie emergency brakes, the ignition circuit will be again operatively connected. By referring to Figs. 'l and 3,
